Well, firstly the book itself (rather than the words). This is a lovely book - the leather or leather effect is beautiful and the stitching very nice. It's a book you'll treasure for years.
The space for the notes of your own is good though I must admit I haven't used it much myself; that was clearly a little ambitious! If you won't use that, buy the non-journal version of course.
As for the writing, well, what can I say?! The wording can be a bit more obscure at times, almost King James like, if not quite that difficult. It does mean that you need more concentration than some other daily readings though so bear this in mind; it's not everyone's cup of tea. That said, the messages themselves are fantastic; very powerful and often challenging. They will challenge you in areas of your lives and make you question your own walk and how devoted you are or aren't. Personally, I don't think that's a bad thing and if you are open minded and wanting to follow Jesus with all your heart, then this book is an excellent manual for doing that.
As a daily reading, subject to the language point above, get it. As for the journal versus normal version, well that's personal preference of course.
